Send Hello messages out each interface to discover directly attached neighbors and build the
adjacency database
Create a link-state packet (LSP) describing the routers local topology. This contains
information about directly connected networks, links to neighbors, and their cost. Send the
LSP and any other LSPs the router has received to its adjacent neighbors.
Collect all the LSPs in the LSDB and run the SPF algorithm to build the forwarding database.
Any time there is a change in the local topology, create a new LSP and flood it to all other
routers. Rerun SPF and rebuild the forwarding database.
When a new LSP is received from a neighbor, update the LSDB, flood the LSP to its neighbors,
and rerun SPF to rebuild the forwarding database.
